A CORPORATON OF vMASSA- PLYING MACHINE rApplication led September 4, 1926. Serial No. 133,609.

My invention relates to a device for plying up stripsy y'of material such as rubberized yfabric or rubber, or a lcombination of the two.

a machine forthis purpose which, while operatingat rarelatively higal speed will accun` rately position `thestrips in desired relation and without distortion. '.A further object is yto provide a Adevice for-this purpose such that the various strips ofv material make minimum contact with "the machine parts, to the end thatthe tension maybecontrolled and a uniyformstretch obtained. Other and furtherV f Vobjects will be apparent from the following specificati-on .and claims.

2 A-plurality of racks 6, one for each plying unit, are mounted along the rear edge of the table 1. As best shown in Figures 2 and 6 v.these racks each comprise an upright 7 relv volvably securedto theftable, as indicated at Salud provided at itsupperend 'with aslotted f ber 12 pivoted at 13 to bar 1l.

It is an'object of my invention to provide fthe locking member engages the slot in stud f 26 are guides 33.

stud 9 journaled in a flat bar 11 projecting rearwardly from bar 3. rllhe rack is releasably held against rotation by a locking mem- One arm of 9., theother arm being connected by rod 14 to a `handle 15 by which the lock kmay be released. Pairs'of spindles project from opposite sides of upright 7. The lower spindles 16 `are adapted to hold a roll of rubber or rub- `material to the previous strip.

, Theplying, units 4 with an exception later described, are exactly similar and a descrip-V tion of one will serve for all. As best shown in Figures 3 and 4 these units comprise a pair 1 of driven rolls 25 and 26, ournaled in a plate 27 secured to bar 3. Rolls25 and 26 are provided, adjacent plate 27, with pulleys 30 and -31 respectively which are driven by belt 32 as later described. Adjacent to rolls L25 and As best shown in'Figure 5 these guides comprise three rods 39, and 41 secured to plate 27, their free ends being maintained in proper position by a head 42. Rod 39'carries a freely rotatable cylindrical roller 34 over which the strips pass between adjustable guide elements 3,5' and 36 adapted to be secured in adjusted position by clamps 37 and 38 engaging rods 40 and 41; A roll 44 is adjustably mounted to ride freely on roll 25.

Roll 44 which is designed to be changed, as

occasion may require, to suit varying widths of material is freely rotatablefon a stub shaft 45 carried by an arm 46 pivoted on bar 47 the latter secured as'at 48 to. plate 27.

e v.Thecompound strip indicated in Figure 3 byzdotted line l comes tothe plying units.

lhile one side of the rack 21 is Y over guide 33 adjacent roll 26, passes under roll 26 and over roll 25 aga-inst which it is maintained in position by roll 44. The strip 51 to be added by the particular plying unit passes from rack 6 (see Figure 2) beneath a milled roll 52 secured on the main drive shaft 53. From roll 52 strip 51 passes around a freely rotatable guide roll 54 adjustably mountedat 55 V(Figurcs 3 and 4\ on an arm 56 secured to an upright 2. After leaving roll 54vthc web 5l is turned through an angle of 900. passing upwardly to guide 33 adjacent roll 25, thence around roll 25 and beneath strip 50 to which it adheres.

The first strip fed to the machine enters the machine at the right hand end as shown in Figure 1, passes through a guide 33 such as has been described, and over a single roll 57 to the first plying unit. Between each plying unit is positioned an adjustable guide 58 mounted on a. rod 59 secured to bar 3. As

the compound strip passes each successive plying unit a strip is added to the under surface, the successive strips being lettered a to c inclusive in Figure 9 which diagrammatically shows the operation as a whole.

lt is sometimes desirable to add a strip f in reverse order, that is on top of rather than beneath the previous strips, so as to overlap the edges of one or more of the previously plied strips, and l provide means for accomplishing this in connection with the last plying unit (the left hand unit as viewed in Figure 1). rl`his means is best shown in Figure 7, and in addition to the mechanism of the plying unit just described, comprises a cylindrical guide roller 60 supported from a block 61 adj ustably secured to an extension of bar 47 A similar guide roller 62 is supported from a block 63 also adjustably mounted on bar 47. Directly beneath roller 62 is a guide member 64 secured to block 63. A loop shaped guide 65 is secured to the guide unit 33 adjacent roll 26. As in the operation previously described the compound strip passe-s over guide 33, then beneath roll 26 and over roll 25. The strip f to be applied to the top of the compound web passes upwardly from its roll 54, untwisted, through loop 65 over rollers 60 and 62, is twisted through 90 between roller 62 and guide 64 and from the latter passes to its position on top of the compound web.

' lt is to be noted that the rolls 52, 25 and 26 move the strips forward by surface Contact only, the rolls 44 exertingV only sufficient pressure to maintain the strips in relative. position and assure adhesion of the strips if the stock is dry, but under ordinary circumstances may be omitted. VIt is desirable, both to maintain the strips in uniform contact with the rolls 52, 25 and 26 and to impart a slight stretch to the strips, that a. certain amount of tension be applied to the latter and this is accomplished by driving rolls 25 and 26 of the last plying unit at a slightly increased speed, as by making the pulleys of these rolls slightly smaller than those by which the preceding rolls are driven, as shown at 30 and 31 in Fig. 1a. This applied tension is substantially uniformly distributed back through the various plying units since while itV acts with greatest force at the units immediately preceding that at which it is applied the compound web with the addition of each strip becomes correspondingly stiffer with the result that while the applied tension at the farthest unit is less it prdduces substantially the same eifect.

The completed compound strip passes from the last plying unit over a roll and downdownly to a wind-up mechanism. As shown in Figure 1 roll 70 is carried by block 68 threaded on a screw 69 provided with crank 81 by which the position of roll 7 0 may be adjusted in an obvious manner.

The wind-up mechanism is best shown in Figure 2. A roll of suitable liner material 71 is mounted on a reel 72 carried by a bracket 73 secured to the main frame. From reel 7 2 the liner passecl over a suitable guide 74 extending from a bracket 75 secured to the frame. Guide 74 forms the pivot for a bell crank lever 76. one arm of which carries a roll 77, the other arm being connected by spring 78 to the frame. Spring 78 acts to j ss roll 77 against a roll 78 mounted on the end of main drive shaft'53. From guide 74 the liner passes around roll 77 thence around roll 78 to a'wind-up roll 79V carried by a spindle 80 ournaled in the main frame. rllhe compound web passes from roll 70 through guides 82 and around roll 83 to the top of roll 78 where it meets the liner. Guides 82 and roll 83 are adjustably secured to a bracket 84 suitably secured to table 1.

Power for driving the machine is furnished from a metor 9G secured to the underside of the table 1, see Figures 1 and 2. The shaft of the motor carries a sprocket 91 connected by a sprocket chain 92 to sprocket 93 on the main drive shaft 53. Belt 32 which drives the plying rolls passes around a pulley 94 positioned centrally of shaft 53, passing from pulley 94 about idle pulleys 95 to the plying roll pulleys, as will be clear from Figure 1. rllhe use of a belt for driving` rolls 25 and 26 renders the drive of each unit substantially independent as the belt may slip on the pulleys if the resistance varie lind-up spindie 80 'is driven by a sprocket chain 96 passing around sprockets 97 and 98 carried respectively by the spindle 8O and main drive shaft 53, sprocket 97 being connected to spindle 8O through a slip clutch indicated at 89.

The machine is conveniently controlled by a switch box 100 (see Figures 1, 2 and 8) provided with stop and start buttons 101 and y 102 and a reduced speed button 103. These buttons arey operated from a bar 10aL running the length of the machine and slidably and rotatably supported in brackets 105 secured to table 1. Bar 10a vcarries arms 106 and 10'? adapted to respectively operate buttons 101 and 102 upon the reciprocation of rolls, the rolls of each pair being spaced fromv each other in the direction of strip travel and positioned. to make arcuate contact with opposite sides of a moving strip oit' material and means associated with one roll of-,each pair of feed an additional strip of material between that roll and the iirst mentioned strip to progressively form a multi-ply strip.
